Karen Casselman Lesson Plan 3 – SMART Math Tools Software INTC 5320 February 16, 2010 OBJECTIVE: 7-4.5 Classifying and Measuring Angles. Student will be able to identify and classify angles as acute, obtuse, right or straight. Student will be able to measure and construct angles using a protractor. Students will be able to utilize the SMART Math Tools software protractor to measure angles using the interactive white board. ENDURING UNDERSTANDINGS: Students will understand that measuring objects affects our everyday life. Students will understand that geometry offers powerful tools for representing and solving problems in all areas of mathematics, in other school subjects, and in everyday applications. Students will understand that there are appropriate units for measuring angles. Students will understand that what we measure affects how we measure it. DO NOW: Selected Questions taken from Spiral Review, Open Ended Test Prep and Logical Thinking. ACTIVITIES: Do Now, Review Homework, Notes and Examples. Students must have prior knowledge of how to name angles. Demonstrate how to use a protractor to measure an angle. Allow the students to measure and construct various angles using the protractor and the SMART Math Tools Software. Indicate the vertex point in the lower middle part of the protractor. Show the zero line for the outside scale and the zero line for the inside scale. Show the outside and the inside scale. Use the protractor in the SMART Math Tools software to drag angles open and closed and discuss the two different measurements on the tool. Discuss how to tell which number to use (by classifying the angle or by working with the protractor from 0). Use several different angles and have the students construct their own on the SMART Board. Measure angles in both directions and try the two different zero start points. Use the ruler in the Math Tools Software to construct two rays as angles and measure angles of various degrees. Vocabulary: Vertex, Angle Symbol, Degrees, Protractor, Straight, Acute, Right and Obtuse Angles. Materials needed: Protractor, paper, communicators, SMART Board and SMART Math Notebook Tools (available for a 30 day free trial) GUIDED PRACTICE: Teacher will first demonstrate use of the actual protractor and use of the virtual protractor and ruler in the Math Tools Software. Teacher created notes and examples customized to match student needs and content. INDEPENDENT PRACTICE: SEARCH Lesson 7-4.5 pages 156 and 157.
